TPS767

SLVS208J –MAY 1999–REVISED AUGUST 2015

TPS767xxQ Fast-Transient-Response 1-A Low-Dropout Linear Regulators

1 Features 2 Description

This device is designed to have a fast transient

• 1 A Low-Dropout Voltage Regulator

response and be stable with 10 µF low ESR

• Available in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-

capacitors. This combination provides high

V, 3.3-V, 5.0-V Fixed Output and Adjustable

performance at a reasonable cost.

Versions

Because the PMOS device behaves as a low-value

resistor, the dropout voltage is very low (typically

4 Description (Continued)

The RESET output of the TPS767xx initiates a reset in microcomputer and microprocessor systems in the event

of an undervoltage condition. An internal comparator in the TPS767xx monitors the output voltage of the

regulator to detect an undervoltage condition on the regulated output voltage.

The TPS767xx is offered in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, and 5.0-V fixed-voltage versions and

in an adjustable version (programmable over the range of 1.5 V to 5.5 V). Output voltage tolerance is specified

as a maximum of 2% over line, load, and temperature ranges. The TPS767xx family is available in 8-pin SOIC

and 20-pin PWP packages.
